Most people, according to a national survey by MarketingSherpa, like to get their communication from companies from print ads. Behind print ads (47%) is email on smartphone (37%), radio ads (24%), text messages (20%), billboards (17%), none (15%), in-person (15%), company's mobile app (12%), location-based promotions (9%), other (9%), push notifications from apps (6%), transit ads (5%) and finally in-app ads (4%).
What's striking is how people just don't want mobile ads though they don't mind email on their phones. I think this speaks to peoples' disdain for ads that get in the way.
The study also asked what peoples' prefered way of receiving updates and promotions. There mail got the highest percentage at 54 percent with email (though at a frequency they chose) at 49 percent. Company websites came in at 38 percent and only 20 percent wanted it on social media. This underscores the danger in using social media for brazen commercial purposes.
